Who Discovered It

The slope formula determines the position of a line with respect to its “x” and “y” coordinates. This mathematical calculation is the concern of Analytical Geometry which solves linear and geometric problem with the aid of Algebra. Thus, to the question who discovered the slope formula, it is necessary to look into who started Analytic Geometry. Rene Descartes 1596 Rene or Renee Decartes is the father of Analytical Geometry. He was a French mathematician, physicist, philosopher, and theologian. Many mathematics experts acknowledge him as the man who discovered the slope formula. He was said to have provided a method to solve the problem of lines and slopes in mathematics by his prowess in Algebra and Geometry. The basic slope formula is y=mx+b while the more complex point-slope formula is y-yl=m(x-x1). Because Descartes is the father of Analytical Geometry and this subject centers mostly on lines and slopes, he was the first to introduce solutions to slopes and linear problems....

Considered as one of the most abundant elements in our body, magnesium is an alkaline earth metal that plays an essential role in the functioning of biological polyphosphate compounds such as DNA, ATP and RNA. This element is also important to plant growth because it is the chlorophyll’s center. Aside from these, the element has other medical, agricultural and industrial uses. To know more about this element, it is best to start with the history of the discovery of magnesium. Historical Background Who discovered magnesium? Based on records, the metal was extracted and discovered in 1808 in England by Sir Humphry Davy. He extracted the element from the mixture of mercury oxide and magnesia with the use of electrolysis. Davy named the element magnium, however, it was later on called magnesium by other scientists. Even if Davy was credited for the discovery of the alkaline earth metal, Epsom salt, a compound form of the element was already used by a farmer in the country to heal rashes as...

Introduction A magnet is an object that produces a magnetic field. It attracts certain other objects to it, and repels other magnets Because magnets have been known to man for so long, it is inevitable that legends have formed regarding its discovery. The word “magnet” is from a Greek term meaning “Magnesian rock.” Legends of the Discovery of Magnets One story tells how a shepherd named Magnes discovered magnet about 2,000 BC. He was guiding his sheep along the pastures of Magnesia in northern Greece. Now Magnes was carrying a shepherd’s rod with a metal tip, and his shoes had nails in them. He stepped on a big black rock and next thing he knew, both his rod and shoes got stuck on the rock by their metallic parts. Perplexed, the shepherd got out of his shoes and dug up the ground. He found loadstones underneath. Loadstones are naturally magnetic due to a substanc3e known as FE304. The Greeks later renamed the stone magnesia after its founder or the area where it was discovered. Historical...

Known as a chemical element that is identified with the atomic number of 28 and symbol of Ni, nickel is a metal that is ductile and hard. This element is classified under the transition metals. The metal is usually present in alloys like taenite and kamacite. It is also present in iron meteorites. Because of the distinct characteristics or properties of this element, it is widely used in producing metal apparatuses. In order to know more about this element, it is best if we start with the history of the discovery of nickel. Historical Background Who discovered nickel? This transition element was discovered by Swedish chemist Axel Fredrik Cronstedt in 1751. The discovery of the element happened when the chemist isolated copper from niccolite. Instead of extracting the metal, he isolated another element with silvery white color that Cronstedt named nickel. Even if Cronstedt was recognized as the scientist who discovered the element, there were evidences, which proved that nickel was used...

Mercury, be it the element or the planet, is quite elusive when it comes to its discoverer. But at least, as far as who discovered mercury the element is concerned, there’s a name worth mentioning. The First Unnamed Discoverers The Babylonians, among the first people groups of early civilization, is credited to be the first to put on record the use of the element mercury. This was some 3000 years ago when it was mixed freely with other products. It was then sometimes added in creams and ointments in dangerous proportions because it was not yet known then as a chemical element. At times poisoning was the result. The discovery of mercury as an element was in the 18th century. Incidentally, at about the same time, also 3000 years ago, the Sumerians discovered the planet Mercury. Like the Babylonians who discovered mercury and put in many records but not as an element, the Sumerians recorded the planet mercury quite a lot. It could be said that both element and planet had probably started...
